How to Enlarge an Image

You have downloaded from an old phone some photos taken a long time ago and, alas, they seem too small to be imprinted on paper! For this reason, would try to enlarge them using some program suitable for the purpose but, given your lack of experience in the field, just you would not know where to start.

How do you say? Have I identified your problem perfectly? In that case, know that you are in the right place, at the right time! In the course of this guide, in fact, I will explain to you in detail how to enlarge an image with some of the most famous photo editing programs, using an online service or, again, using the print menu of printers and photocopiers.

Before getting to the heart of this guide, however, I consider it necessary to make a clarification: in order to reduce the "weight" of the images, it is often necessary to apply a compression algorithm, which, in some cases, can also involve the loss of data that is not essential for the final rendering of the photo (algorithms lossy). Unfortunately, images so compressed, if zoomed in too much, can be grainy, blurry or, worse still, have indistinguishable margins. For this reason, the result that can be obtained after resizing an image varies greatly both according to the compression algorithm applied and the level of compression used: keep this aspect in mind before you even proceed!

Programs to Enlarge an Image

If you are trying to understand how to enlarge an image using some of the most popular photo editing software, then this is the part of the guide that best suits you: in fact, below I am going to explain how to proceed in the most common programs of the category.

How to Enlarge an Image in Photoshop

Enlarge an image with the software Photoshop from Adobe is really simple. Let me tell you right away that the steps to take are practically the same on all currently supported versions of the program.

To begin with, open the image of your interest within the program (you can do this via the menu File> Open or the menu Photoshop> Open, top left) and, once the file is loaded, click on the menu Image and select the item Image size ..., which is inside.

Once this is done, use the options available in the window that is proposed to you to define the resizing modes you prefer.

  • Dimensions: select theunit of measure to use for resizing.
  • Fit to: indicates whether to readjust the aspect ratio to the original image size, or to a predefined graphic template.
  • WidthHeight: specify here the new size of the image (to change the unit of measurement, use the drop-down menu next to both items). If you prefer to keep the aspect ratio unchanged, which is recommended to avoid distorting the resulting image, make sure that the chain which combines both options either closed, otherwise click on it to close it. If so, specify the new size for only one of the two lengths, as the other will automatically change accordingly.
  • Resolution: indicates here the new resolution to be applied to the image, in pixels per inch or pixels per centimeter.
  • Resample: Place the check mark next to this item to resample it and, if necessary, specify the mode using the corresponding drop-down menu.

If you are not very experienced, I advise you to intervene exclusively on the fields WidthHeight and leave the automatic image aspect ratio active. To view the "weight" of the same after the resizing operation, take a look at the wording Image size which stands at the top of the window.

When you are satisfied, click on the button OK, to apply the specified changes and resize the image, which you can later save using the menus File / Photoshop> SalvaFile / Photoshop> Export, top left.

If the result obtained is not satisfactory for you, you can cancel the operation just carried out by pressing the key combination Ctrl + Z (cmd + z, on Mac), or by going to the menu Edit> Reset Image Size.

Alternatively, you can increase the size of the image by using the tool Free transformation Photoshop: to do this, select the entire canvas using the tool selection (l'icona del dashed rectangle) located in the toolbar, right click on the image and choose the item Free transformation from the proposed context menu. In this way, you have the possibility to zoom in, out, distort and rotate the image, altering its edges with the mouse.

If you are interested in learning more about how Photoshop works, I invite you to take a look at the in-depth tutorial I have dedicated to it; if you would like to further deepen your knowledge of the program and learn how to perform even more manipulation interventions, I invite you to read the guides that I have collected in the specific section of this site.

However, keep in mind that, in most cases, the recalculation of the aspect ratio is not automatic and the image could be significantly deformed, so I recommend that you perform the scaling calculations manually.

Note: if you prefer, you can also resize the image via css, using a code similar to .

How to Enlarge an Image with Paint

If you need to enlarge an image, use Windows but you have no way to install one of the solutions I mentioned earlier, you can get a respectable result using Paint, the evergreen graphics program included “standard” in the Microsoft operating system.

How to Enlarge an Image Without Losing Quality

As I explained to you in the opening bars of this guide, the rendering of an enlarged image varies greatly according to the compression algorithm chosen and the level of compression applied during the rendering phase: therefore, it is very likely that images with "weight" relatively low may, during enlargement, be grainy or less sharp than the original.

How to Enlarge an Image and Print It

If you need to enlarge an image and print it without using any accessory software, know that you can achieve this through both the Windows and macOS print panel. If, on the other hand, you have a photocopier available, you can use the special integrated function to enlarge a paper document. Below I'll explain all the details.

How to Enlarge an Image with the Printer

For enlarge an image with the printer, by avoiding opening it with a third-party program, you can use Windows and macOS print settings.

It was used Windows, first locate the fillet of your interest, right click on its icon and choose the item Print from the menu that is proposed to you. Now, using the print screen, define the settings that suit you: select the item Fit the image to the frame to ensure that the image does not go beyond the edges of the sheet and use the previews located in the right sidebar to set the magnification level you want. For example, if you want the image to occupy the entire surface of the sheet, you can choose the option Full page photo.

Now, I recommend that you select the option Excellent give menu to tendin Print quality, to try to "correct" any grain in the photo (with a slightly higher ink consumption), indicates the format of the sheet that will host the imprinted image (eg. A4) and, after selecting the printer to use from the menu of the same name, click on the button Print to start the process.

If you own a Poppy, you can act through a procedure rather similar to that already seen for Windows: to start, open theimage you are interested in printing and press the key combination cmd + p (or use the menu File> Print, top left) to open the panel dedicated to print settings.

Pray click on your button Show details and, after choosing the dimensions and l 'orientation of the sheet, put the check mark next to the item Fit to scale and choose if print the whole image in the sheet, following its dimensions, or fill the whole page resizing the image.

If, on the other hand, you prefer to manually indicate a scale factor, put the check mark next to the item Ladder and specify the percentage of enlargement to apply, in the adjacent text box. When you are satisfied with the result (which is shown in real time in theprint Preview), press the button Print located at the bottom right.

Note that both methods seen in this section do not alter the original image, which will keep its size.

How to Enlarge an Image with the Copier

Be aware that most devices of this type allow you to perform a similar operation. Clearly, it is not possible for me to provide you with the steps to follow for all existing models on the market, because the functionalities differ depending on both the manufacturer and the operating system on board the copier.

In general, what you need to do is insert original printed image under the copier lens or in the modulo ADF, press the button to make one Copy and, after entering the number of copies to be made, access the options copy by pressing the appropriate button.

Once this is done, access the section relating toEnlarge / Reduce image, indicates that you want to apply a factor ofmagnification and use the options that are proposed to you to define the ratio, or the percentage.
